This volume comprehensively demonstrates Thomas Aquinas' unique contribution to theology, and is the first systematic presentation of the hermeneutics and sources of Biblical Thomism.Divided into 4 sections, this handbook first surveys the methodological issues and exegetical methods employed by Aquinas. The second part deals with both the major sources of Aquinas' exegesis, as well as the influence of his exegesis. The third part gives an overview of the content and hermeneutical principles present in Aquinas' biblical commentaries - Isaiah, Jeremiah, Book of Psalms, Job, Matthew, John, and Pauline Epistles. The final part discusses systematic themes; explaining how and why Aquinas bases his systematic account of these themes in Scripture, and how this compares to contemporary and ecumenical approaches.
